Two noble mountains fired the fancies of the native races of Mexico before the Aztecs. Quiescent at present they were within historic time quite active. They are the "'Star Mountain," or Citlaltepetl, and the "Smoking Mountain" or Popocatepetl. Both tower above the great Mexican tableland, itself 7,000 feet above tide-level; the first named on its eastern margin and the last mentioned in the central part overlooking the capital city.
